Coming from ancient Chinese classics, the idiom “a frog in a well” paints a vivid metaphor. Confined inside a well, the frog mistakes the small circle of sky for the whole universe. It describes people trapped by their limited experience, unaware of the wider world, and serves as a reminder to avoid narrow‑minded complacency.
Daoist sage Lie Yukou declined grain from minister Ziyang, foreseeing peril from political favor gained via others’ words. Later Ziyang was killed in a revolt, leaving Liezi unharmed. He lived in seclusion and authored the classic Daoist work Liezi.
